[现状]绵羊肺炎支原体(Mycoplasma ovipneumoniae)是引起绵羊和山羊呼吸系统疾病的主要病原之一,病羊以咳嗽、气喘、流鼻液、消瘦等为主要临床症状.[问题]由于该病原具有广泛的寄主范围,病程长,体外培养困难,对抗菌药物的敏感性难以测定,致使临床选药困难,用药依从性差.因此,目前该病防控缺乏便捷且行之有效的措施,具有较高的病死率,一旦发病对羊产业造成巨大经济损失.[对策]目前有效防控措施为疫苗免疫,但缺乏针对性强的商业化市售疫苗.根据目前抗病育种研究,可以针对绵羊肺炎支原体培育新抗病绵羊品种.[结论]疫苗防控是快速有效的防控措施之一,但由于流行病原无交叉保护性,且成本较高,无法满足新疆羊产业发展需要,因此,培育抗绵羊肺炎支原体的绵羊新品种十分必要且意义深远.
[Background]Mycoplasma ovipneumoniae is a primary causative agent of respiratory illnesses in sheep and goats,leading to clinical manifestations such as coughing,wheezing,rhinorrhea,and wasting.The control of this pathogen poses a significant challenge due to its broad host range,prolonged duration of illness,obstacles in achieving successful in vitro cultivation,and variable antimicrobial sensitivity profiles.[Challenges]This complexity in managing Mycoplasma ovipneumoniae infections has led to considerable economic losses within the ovine sector.Current treatment strategies are hampered by these difficulties,highlighting the need for more effective control measures.[Strategies]Presently,immunization through vaccines is acknowledged as an efficient preventive strategy.However,the limited availability of commercial vaccines hampers their utility.Emerging studies advocate for the development of sheep breeds genetically resistant to Mycoplasma ovipneumoniae.Vaccination,while rapid and efficacious,fails to offer universal protection against all prevalent strains and is economically untenable,thus inhibiting the progress of the sheep industry in regions such as Xinjiang.[Conclusion]To ensure a sustainable solution and mitigate the financial burden,strategic breeding for intrinsic resistance to Mycoplasma ovipneumoniae infection in sheep populations presents a more practical and promising long-term approach to disease management.
